I am new to all this and trying to figure out what this motor can do.
To determine what pump Impeller is best for a new rebuilt JG Berkeley I am going to install. With a Place diverter. Into my 1978 Centurion 18Ft Bubble with light Hull.
I think it has an A in the JC Berkeley now??
It pulls approx 5200 RPM with the old JC doing about 69MPH with good hole shot (Cavitation is bad if you jump on it from a stand still)
